subject: The Phone Mold Process Analysis [print this page] Housing materials commonly used Housing materials commonly used
ABS: High fluidity, inexpensive and applicable to the requirements are not too high on the strength member (not directly affected by the impact, does not bear the structural durability test member reliability testing). Such as mobile phones within the support frame (Keypad frame, LCD frame). There is generally used in plating parts (such as buttons, side buttons, navigation keys, electroplating, decorative pieces, etc.).
PC+ABS: Good fluidity, good strength, and affordable. Apply to the vast majority of cell phone case, as long as the structural design optimization, strength is guaranteed.
PC: The high strength, expensive, and poor fluidity. Higher strength requirements apply to housing (such as clamshell phone with two casing and the shaft, without standard rails slide machine module rail and slide the two shells, currently designated must with a PC material).
2. Silicone key characters making method
Screen printing: a printing surface and the bottom, the printing surface when the general first spray the surface of the keys, in the above silk screen font and symbols, and then spray to protect the oil. Printed on the bottom are generally transparent buttons, screen printing hollow words cover a solid background color and silk screen font cover background . The font Corrosion on the steel plate For the key surface cambered large Pad method can be used, ink printing to the surface of the keys with a plastic head, pad printing used a lot in the toy industry.
2. If the character requires light effect, most of the spraying and laser carving a transparent button after injection, in key surface spray ink, then laser can be opaque character, then spray a layer of protective oilcan. Asked to see the red symbol in the top surface of the key pad red, need to be printed to the entire surface, spraying the surface of the ink and then wiped out in red, other colors similar.
3. Need to plating effect buttons can do water electroplating and vacuum plating, now many direction key to do Yin and Yang pattern effect electric mold, so to make a clear boundary, appearance beautiful, is the place cannot achieve this effect. Bi-color injection general use in a key to have pervious to light and plating buttons, PC is not plating, abs to electroplating, bi-color injection requirement is the PC and abs plastic injection, electroplating together after the abs place is plating effect, and part of the PC can be pervious to light. Vacuum plating can be made opaque symbols, but compared to vacuum plating, plating effect is not the best.
Mobile phone keypad surface mine carved is the keys painted surfaces processing of text processing. General for diameter 0.04-0.06 size, will the characters use spacing 0.04-0.06 line filling. Give laser made a path, and the path will paint cutting off it.
